Bug Description

For many reasons (testing, security, safety, simplicity, etc), I would like to be able to run kazaam directly from an extracted tarball or bzr checkout.

Other python applications such as Pitivi, GTG and Specto allow doing exactly that. For example:
- in pitivi's git checkout you can simply do "bin/pitivi" (not /bin/pitivi) and it detects that you are running it from the dev environment
- in lp:specto, you can run "./launch.sh" to launch specto without installing.

As Poepy mentioned, you can run it alright, there's just one catch. If you don't have it installed, you will not see program icons and indicator icons. Unfortunately this is a problem with Application Indicators (see #657857).
